Answer
Steroid hormones exert their effect primarily by **finding receptors in the cytoplasm and then regulating transcription and translation.**<br /><br />Here's why the other options are incorrect:<br /><br />* **Interacting with receptors on cell membranes:** Steroid hormones are lipid-soluble, allowing them to pass through the cell membrane. Their receptors are primarily located *inside* the cell, not on the membrane. Peptide hormones, on the other hand, typically bind to cell surface receptors.<br /><br />* **Initiating formation of cyclic AMP/GMP:** These are second messenger systems typically activated by *peptide* hormones binding to membrane receptors. Steroid hormones exert their effects through direct interaction with DNA, influencing gene expression.<br />
